Organ Pipe Cactus National Monument

Detailed Description

Organ pipe cactus are rare in the Sonoran desert in the U.S. They can only be found in and around Organ Pipe Cactus National Monument, shown here. The distribution of Organ Pipe Cactus is limited due to lack of tolerance for cold temperatures. The biota of the Sonoran desert is particularly senstive to disturbance. Soils often erode quickly once vegetation is removed. The USGS RAMPS program works with the National Park Service and other land managers to restore the Sonoran desert landscape after disturbance.
